    1. General Description

    1.1 Charge current up to 35A and PV voltage up to 150V The SmartSolar MPPT 150/35 charge controller is able to charge a lower nominal-voltage battery from a higher nominal voltage PV array. The controller will automatically adjust to a 12V, 24V or a 48V nominal battery voltage.

    1.2 Ultra-fast Maximum Power Point Tracking (MPPT) Especially in case of a clouded sky, when light intensity is changing continuously, an ultra fast MPPT controller will improve energy harvest by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers.

    1.3 Advanced Maximum Power Point Detection in case of partial shading conditions If partial shading occurs, two or more maximum power points may be present on the power-voltage curve. Conventional MPPTs tend to lock to a local MPP, which may not be the optimum MPP. The innovative SmartSolar algorithm will always maximize energy harvest by locking to the optimum MPP.

    1.4 Outstanding conversion efficiency No cooling fan. Maximum efficiency exceeds 98%. Full output current up to 40°C (104°F).

    1.5 Extensive electronic protection Over-temperature protection and power derating when temperature is high. PV short circuit and PV reverse polarity protection. PV reverse current protection.

    1.6 Internal temperature sensor Compensates absorption and float charge voltages for temperature. (range 6°C to 40°C)

    1.7 Optional external voltage and temperature sensor (range -20°C to 50°C) The Smart Battery Sense is a wireless battery voltage-and- temperature sensor for Victron MPPT Solar Chargers. The Solar Charger uses these measurements to optimize its charge

    parameters. The accuracy of the data it transmits will improve battery charging efficiency, and prolong battery life. Alternatively, Bluetooth communication can be set up between a BMV-712 battery monitor with battery temperature sensor and the solar charge controller.

If a different system voltage is required at a later stage, it must be changed manually, for example with the Bluetooth app, see section 1.11. 1.9 Flexible charge algorithm Fully programmable charge algorithm, and eight preprogrammed algorithms, selectable with a rotary switch. 1.10 Adaptive three step charging The BlueSolar MPPT Charge Controller is configured for a three step charging process: Bulk – Absorption – Float. 1.10.1. Bulk During this stage the controller delivers as much charge current as possible to rapidly recharge the batteries. 1.10.2. Absorption When the battery voltage reaches the absorption voltage setting, the controller switches to constant voltage mode. When only shallow discharges occur the absorption time is kept short in order to prevent overcharging of the battery. After a deep discharge the absorption time is automatically increased to make sure that the battery is completely recharged. Additionally, the absorption period is also ended when the charge current decreases to less than 2A. 1.10.3. Float During this stage, float voltage is applied to the battery to maintain it in a fully charged state. 1.10.4. Equalization See section 3.8

    1.11 Remote on-off The MPPT 150/35 can be controlled remotely by a VE.Direct non inverting remote on-off cable (ASS030550300). An input HIGH (Vi > 8V) will switch the controller on, and an input LOW (V < 2V, or free floating) will switch the controller off. Application example: on/off control by a VE.Bus BMS when charging Li-ion batteries. 1.12 Configuring and monitoring Configure the solar charge controller with the VictronConnect app. Available for iOS & Android devices; as well as macOS and Windows computers. An accessory might be required; enter victronconnect in the search box on our website and see the VictronConnect download page for details. For simple monitoring, use the MPPT Control; a panel mounted simple yet effective display that shows all operational parameters. Full system monitoring including logging to our online portal, VRM, is done using the GX Product range

    2. IMPORTANT SAFETY INSTRUCTIONS

    SAVE THESE INSTRUCTIONS - This manual contains important instructions that shall be followed during installation and maintenance.

    ● Please read this manual carefully before the product is installed and put into use. ● This product is designed and tested in accordance with international standards. The equipment should be used for the designated application only. ● Install the product in a heatproof environment. Ensure therefore that there are no chemicals, plastic parts, curtains or other textiles, etc. in the immediate vicinity of the equipment. ● The product is not allowed to be mounted in a user accessible area. ● Ensure that the equipment is used under the correct operating conditions. Never operate it in a wet environment. ● Never use the product at sites where gas or dust explosions could occur. ● Ensure that there is always sufficient free space around the product for ventilation. ● Refer to the specifications provided by the manufacturer of the battery to ensure that the battery is suitable for use with this product. The battery manufacturer's safety instructions should always be observed. ● Protect the solar modules from direct light during installation, e.g. cover them. ● Never touch uninsulated cable ends. ● Use only insulated tools. ● Connections must always be made in the sequence described in section 3.6. ● The installer of the product must provide a means for cable strain relief to prevent the transmission of stress to the connections. ● In addition to this manual, the system operation or service manual must include a battery maintance manual applicable to the type of batteries used.

    3. Installation

    WARNING: DC (PV) INPUT NOT ISOLATED FROM BATTERY CIRCUIT CAUTION: FOR PROPER TEMPERATURE COMPENSATION THE AMBIENT CONDITION FOR CHARGER AND BATTERY MUST BE WITHIN 5°C. 3.1. General ● Mount vertically on a non-flammable substrate, with the power terminals facing downwards. Observe a minimum clearance of 10 cm under and above the product for optimal cooling. ● Mount close to the battery, but never directly above the battery (in order to prevent damage due to gassing of the battery). ● Improper internal temperature compensation (e.g. ambient condition battery and charger not within 5°C) can lead to reduced battery lifetime. We recommend using a direct battery voltage sense source (BMV, Smart Battery Sense or GX device shared voltage sense) if larger temperature differences or extreme ambient temperature conditions are expected. ● Battery installation must be done in accordance with the storage battery rules of the Canadian Electrical Code, Part I. ● The battery and PV connections must be guarded against inadvertent contact (e.g. install in an enclosure or install the optional WireBox M). 3.2 Grounding ● Battery grounding: the charger can be installed in a positive or negative grounded system. Note: apply a single ground connection (preferably close to the battery) to prevent malfunctioning of the system. ● Chassis grounding: A separate earth path for the chassis ground is permitted because it is isolated from the positive and negative terminal. ● The USA National Electrical Code (NEC) requires the use of an external ground fault protection device (GFPD). These MPPT chargers do not have internal ground fault protection. The system electrical negative should be bonded through a GFPD to earth ground at one (and only one) location. ● The charger must not be connected with grounded PV arrays. (one ground connection only) ● The plus and minus of the PV array should not be grounded. Ground the frame of the PV panels to reduce the impact of lightning.

    WARNING: WHEN A GROUND FAULT IS INDICATED, BATTERY TERMINALS AND CONNECTED CIRCUITS MAY BE UNGROUNDED AND HAZARDOUS. 3.3. PV configuration (also see the MPPT Excel sheet on our website) ● Provide a means to disconnect all current-carrying conductors of a photovoltaic power source from all other conductors in a building or other structure. ● A switch, circuit breaker, or other device, either ac or dc, shall not be installed in a grounded conductor if operation of that switch, circuit breaker, or other device leaves the grounded conductor in an ungrounded state while the system remains energized. ● The controller will operate only if the PV voltage exceeds battery voltage (Vbat). ● PV volta
